Connective Tissue

Question 1

What is this?

Answer 1

Connective Tissue Proper

Question 2

What is a Fibroblast?

Answer 2

Cells that create the tissue

Question 3

What are Collagen Fibers?

Answer 3

Thick white fibers that are very strong and are made by the fibroblasts through protein synthesis.

Question 4

How does a Capillary relate to Connective Tissue Proper?

Answer 4

The more room in the matrix = more blood vessels found

Question 5

What is a Mast Cell?

Answer 5

A type of WBC (basophil) commonly found in CT. Releases histamine or heparine (anticoagulant).

Question 6

What are other names for WBC?

Answer 6

Neotrophil or monocyte

Question 7

What are Reticular Fibers?

Answer 7

Small collagen fibers secreted by fibroblasts

Question 8

Explain what a Matrix, or IF, is.

Answer 8

Fluid filled space between cells.

Question 9

What are some identifiers of Adipose Tissue?

Answer 9

• Very Vascular
• Rule Breaker: Has Cellularity
• Vascule with in cell to store triglycerides

Question 10

What are some identifiers of Loose Reticular?

Answer 10

• Makes up framework of a hollow organ
• Very vascular to filter the lymphs

Question 11

What are some identifiers of Dense Irregular?

Answer 11

• Fibroblasts with lots of Collagen Fibers

Question 12

What are some characteristics of Fibrocartilage?

Answer 12

• Alt. rows of cells, matrix, and fibers create a tissue that can absorb a lot of forces. (Similar to a spring)

Question 13

What are some characteristics of Elastic Cartilage?

Answer 13

• Strong like hyaline but elastic fibers allow it to return to original shape after bending
• Ex: External ears, epiglottis

Question 14

What are characteristics of Osseus ( Bone Connective Tissue)?

Answer 14

• Gel like matrix of the cartilage has Ca++ Salts added making the matrix even harder
• 2 types: Compact and Spongy
• Very vascular - has canals containing blood vessels runnning through matrix to give nutrient delivery (compact) or houses red marrow (spongy)
• Large nerve supply
• High amount of collagen fibers for strength
• Osteoblasts, osteoclasts, osteoples

Question 15

What is a Lamella?

Answer 15

A ring of cells.

Question 16

What is an Osteocyte?

Answer 16

A bone cell.

Question 17

What is a Lacurae?

Answer 17

A little lake where cells live.

Question 18

What are Canaliculi?

Answer 18

Tiny canals that carry nurients from one lacurae to another.

Question 19

What do the Haverson Canal or Central Canal do?

Answer 19

Carries blood vessels and nerves to the groups of lamella belonging to that group (Haversion system of osteon).

Question 20

What does the Volkmann’s or Perforating land do?

Answer 20

Travel at right angles connecting osteons, periosteum, and medalany cavity.

Question 21

What are the characteristics of Blood?

Answer 21

• Matrix is a fluid known as Plasma
• Filters are used for Bloodclotting
  
  • Stay in inactive form and do not become visible until the clotting process is activated
• More matrix than cells
• Cells originate from Red Bone Marrow by Hemocytoblasts
  
  • Erythrocytes = RBC’s
  • Leukocytes = WBC’s
  • Thrombocytes = Platelets

Question 22

What are characteristics of Connective Tissue?

Answer 22

• Most common tissue
• More matrix than cells
• Fibers running through the matrix
• Job is to hold things together and provide structure and support
• Vasculartiy varies with different connective tissues
• Cells are named by the tissue they make
• Ex: Adipose tissue, bones, ligaments, cartilage, loose connective tisse that holds organs together

Question 23

What are Collagen Fibers?

Answer 23

These are one of the strongest proteins the body makes. It is formed by the cell. Vitamin C and the mineral copper are need to form strong collagen fibers - also know as White Fibers.

Question 24

What are Reticular Fibers?

Answer 24

These are the tiny versions of collagen fibers.

Question 25

What are Elastic Fibers?

Answer 25

These fibers can do what collagen cannot do, which is return to their original position once they have been pulled or stretched. These fibers are known as Yellow Fibers.
